Title:
METHOD FOR SENDING AND DETECTING DOWNLINK CONTROL INFORMATION
Document Type and Number:
WIPO Patent Application WO/2010/124628
Kind Code:
A1
Abstract:
A method for sending and detecting downlink control information is provided. A base station carries the downlink control information in a physical downlink control channel, and the physical downlink control channel is sent through a component carrier. The base station carries the first type of downlink control information on the anchor component carrier and carries the third type of downlink control information on the prime component carrier, wherein, the first type of downlink control information carries one or a plurality of the uplink scheduling information, the downlink scheduling information and the uplink power control information of the component carrier in which the first type of downlink control information is located, the third type of downlink control information carries the indication information of the second type of downlink control information, and the second type of downlink control information carries the uplink and/or downlink scheduling information of one or a plurality of component carriers. A terminal detects the first type of downlink control information on the anchor component carrier and detects the third type of downlink control information on the prime component carrier. The method has better scheduling flexibility, compatibility and error code performance, lower blind detection times and lower signaling costs.
